Bug ID: 498921
Summary: DjVu annotation feature neglects to use DjVu’s native
specs for annotation chunks
Classification: Applications
Product: okular
Version: 22.12.3
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: DjVu backend
Assignee: okular-devel at kde.org
Reporter: kdebugs.grokchem at recursor.net
Target Milestone: ---
SUMMARY
Annotations are needlessly lost when saving a file as DjVu.
Some might regard this as a wishlist report but it’s tagged as a bug because
information is needlessly lost. A user could spend some time marking up a
document with a reasonable (and normal) expectation of saving the work in a
single DjVu file. They will be astonished to learn when the try to save that
their work can only be preserved if they change the file format to one that
locks them to a specific app. Then they must choose between portabilty and data
preservation.
STEPS TO REPRODUCE
1. Open an arbitary DjVu file
2. Add a pop-up note
3. File » Save as..
4. change the filetype from `okular` to DjVu
OBSERVED RESULT
This warning emerges:
“You are about to save changes, but the current file format does not support
saving the following elements. Please use the Okular document archive format to
preserve them. Click Continue to save, but you will lose these elements as well
as the undo/redo history.”
EXPECTED RESULT
The DjVu format has a native facility for annotation chunks. So when saving a
DjVu file with annotations okular should comply with the spec and produce a
DjVu file that contains annotations. The `djvused` tool has support for this,
so one option would be to call `djvused`. Another option would be to make
whatever library calls djvused uses to store annotations.
